مسند أحمد

It was narrated that Abu Wa`il said: A man came to ‘Ali (رضي الله عنه) and said: O Ameer al-Mu`mineen, I am unable to pay off my contract of manumission; help me, `Ali (رضي الله عنه) said: Shall I not tell you some words that the Messenger of Allah (ﷺ) taught me, then if you owe debts as great as Mount Seer in dinars, Allah will pay it off for you? He said: Yes indeed. He said: Say: O Allah, suffice me with what You have permitted so that I have no need of what You have forbidden, and make me independent of anyone other than You by Your grace.
